Select the correct combination of gland to its hormone and function.

Options

A. Pituitary gland---melatonin
B. beta cells of Pancreas=-------glucagon
C. Zona glomerulosa ------sex corticoids
D. hypothalamus ----- GnRH

Answer

To solve the question regarding the correct combination of glands to their hormones and functions, we will analyze each option step by step.

### Step-by-Step Solution:

1. **Identify the Gland and Hormone**:
- The question provides a list of glands and their corresponding hormones. We need to identify which gland produces which hormone and what the function of that hormone is.

2. **Evaluate Each Option**:
- **Option 1**: Pituitary Gland - Melanocyte Stimulating Hormone (MSH)
- The pituitary gland has two parts: anterior and posterior. The anterior lobe secretes various hormones, but MSH is secreted by the intermediate lobe, not the pituitary gland as a whole. Hence, this option is incorrect.

- **Option 2**: Beta Cells of Pancreas - Glucagon
- Glucagon is produced by the alpha cells of the pancreas, while beta cells secrete insulin. Therefore, this option is also incorrect.

- **Option 3**: Zona Glomerulosa - Glucocorticoids
- The zona glomerulosa of the adrenal cortex primarily secretes mineralocorticoids, such as aldosterone, not glucocorticoids. Thus, this option is incorrect as well.

- **Option 4**: Hypothalamus - Gonadotropin Releasing Hormone (GnRH)
- The hypothalamus does secrete GnRH, which stimulates the anterior pituitary to release FSH and LH. This is a correct statement, making this option the right answer.

3. **Conclusion**:
- After evaluating all the options, the correct combination is: **Hypothalamus secretes Gonadotropin Releasing Hormone (GnRH)**.

### Final Answer:
- The correct combination of gland to its hormone and function is: **Hypothalamus - Gonadotropin Releasing Hormone (GnRH)**.
